... Additional features include a 100ms Power-On-Reset output, <1µA shut-down current, short-circuit protection, and over-temperature protection. The EL7534 is available in the 10 Ld MSOP package, making the entire converter occupy less than 0.15 in PCB area with components on one side only. Both packages are specified for operation over the full -40° ...

... The output voltage is gradually increased to ensure proper soft- start operation. When the EN pin is connected to a logic low, the EL7534 is in the shut-down mode. All the control circuitry and both MOSFETs are off, and V falls to zero. In this mode, the OUT total input current is less than 1µ ...
